I'm trying to "Put a file with SFTP" (aprox 300mb) in a Job . Uploading manually and small files works fine. I get the following message:

2014/12/16 12:30:25 - Put a file with SFTP 2 - ERROR (version 5.0.4, build 1 from 2014-02-17_08-03-10 by buildguy) : Error while trying to send files. Exception :

Any help or pointers will be greatly appreciated.
